Abstract : The purpose of this study is to investigate the transient behavior of nonreciprocal ferrite devices and coupled networks which are used in wideband radar and communications systems to process signals having wideband spectral content. This investigation should lead to a better understanding of the limitations imposed by the use of these components. This interim report is devoted primarily to the results of experimental and theoretical analysis of the time domain characteristics of typical ferrite devices. The intrinsic behavior of a ferrite is discussed, using an infinite ferrite as a model to analytically develop an expression describing transient wave propagation. The result is a complicated function whose inverse Laplace transform has not yet been evaluated. Experimental results are presented showing the time domain response, insertion loss, isolation, and similar characteristics for selected ferrite device types chosen to evaluate the transient response with the ferrite operating in a variety of magnetization states.
